We're being asked to calculate the Kc for the following reaction:
2 NOCl ⇌ O2(g) + N2(g) + Cl2(g)
To calculate the Kc of the reaction equation, we’re going to use Hess’s Law. We’re going to manipulate the reactions with given Kc value to get the reaction equation with the unknown Kc.
Given the values of K shown below, determine the value of K for the reaction,
2 NOCl <=> O2(g) + N2(g) + Cl2(g)
1/2 N2 + 1/2 O2(g) <=> NO(g) K = 0.063
NO(g) + 1/2 Cl2(g) <=> NOCl(g) K = 0.0829
Give your answer to the nearest whole number
